Cell viability experiments demonstrated that PD-L1 is key to the maintenance of cell viability in TRAIL-treated cells. This indicated that PD-L1 binds to and participates in EGFR activation through miR-429 regulation to antagonize TRAIL-induced apoptosis. This provides a new theoretical basis for the combination of the EGFR monoclonal antibodies including cetuximab, PD-L1 inhibitors, and human recombinant TRAIL in gastric cancer therapy and can filter patients who are currently sensitive to TRAIL treatment.Filariasis is endemic in the tropical and subtropical regions of the world. Lymphatic filariasis presents commonly as hydrocele, lymphocele, lymphadenopathy, pitting edema, elephantiasis, or subclinical microfilaremia. Here, we present a case of filariasis presenting as a retroperitoneal cyst, which was diagnosed on identification of microfilaria in the cyst fluid and cyst wall.Hymenolepiasis is considered the most common tapeworm infection throughout the world infecting 50-75 million people. Hymenolepis diminuta infection is not commonly reported in human beings as compared to Hymenolepis nana because it is primarily a parasite of rats and mice. There are few case reports of H. diminuta in the Indian population. To the best of our knowledge, not a single case of coinfection with H. nana and H. diminuta has been reported from India. We present here a rare case report of coinfection of H. nana and H. diminuta in a 4-year-old male child from a semirural area of India who presented with acute and severe colitis.Hemophagocytic lymphohistiocytosis (HLH) is an unusual multifaceted clinicopathological entity that often remains misdiagnosed and can be fatal if not timely detected or treated. It can be familial or associated with different types of infections, autoimmune disorders, and malignancies. Parasitic infection-associated HLH has been rarely documented in the literature with only a handful of them being reported due to Plasmodium vivax infection. We describe an extremely rare case of pancytopenia induced by HLH resulting from P. vivax infection in a 7-year-old girl, which posed as a diagnostic challenge and led to a therapeutic delay.Amebiasis is an endemic protozoal infection in developing countries. Extra-intestinal involvement in the form of abscess is frequently seen in liver and lungs. The occurrence of amebic brain abscess is a rare and life-threatening presentation of systemic amebiasis. Here, we report a case of a young male who simultaneously presented with amebic liver and brain abscesses. He was successfully managed with intravenous metronidazole, other antibiotics, and drainage of both brain and hepatic abscesses along with supportive measures. The rare occurrence of this simultaneous presentation of amebic hepatic and brain abscess, prompted us to report this case.Wuchereria bancrofti is the major species resulting in filarial cases in India. Filariasis may present with various clinical presentations asymptomatic, microfilaremia, lymphedema, acute adenolymphangitis and chronic lymphatic disease. Microfilariae of W. bancrofti have been detected in various clinical samples, but incidental detection of microfilaria in achylous urine is a rare finding with unexplained pathology. We report a case of microfilaria in achylous urine of a 30-year-old female who presented with pain abdomen and ureteric calculus on ultrasonography.Myiasis is the infestation of live vertebrates (humans or animals) with dipterous larvae. Eristalis tenax, belonging to order Diptera and family Syrphidae, seldom causes accidental myiasis, usually due to ingestion of contaminated food or water by humans. Here, we report a case of intestinal myiasis in a male from Alexandria, Egypt, complaining of frequent passage of small worms in his stool. A larva and a pupa were presented to the laboratory and examined macroscopically, and then studied by a scanning electron microscope. E. tenax (rat-tailed maggots) were diagnosed. Rarely diagnosed worldwide, a case of E. tenax accidental intestinal myiasis was found in a middle-aged adult male from Egypt. https://www.selleckchem.com/products/pf-3644022.html A larva and a pupa were identified and studied macroscopically and by scanning electron microscope.The objective is to determine prevalence and risk factors for soil-transmitted helminth (STH) infection among school-going age children from slums of Bhubaneswar.
Cross-sectional observational study.
Microbiology laboratory of a tertiary care hospital, Bhubaneswar, during May 1-October 30, 2015 (6 months) including 360 children of 3-15 years from two populated slums of Bhubaneswar, assuming STH prevalence - 50%, confidence interval 95% and 10% relative precision. Purposively sampling by house to house visit was adopted to collect stool samples along with risk factors through questionnaires from each child after written informed consent of parents/guardians.
Direct saline mount and egg counting by Kato-Katz (KK) method for STH-positive samples was done.
STH prevalence was 13.3%, more in males (68.8%), and significantly high (62.5%. &lt; 0.05) in school-going children between 6 and 12 years of age. Predominant STH was (56.2%), 15% of parents were illiterate, 80% of houses had toilets, 70% were washing hand with soap and using footwear. STH infection was much less (12.5%) in those practicing handwashing with soap. Fifty percent of children had STH infection even after receiving deworming within the past 6 months. More egg counts - 216 eggs/gram of feces were found in 29 cases by KK method. (56.5%) was predominant among non-STH infections.
STH prevalence of Bhubaneswar slums was minimum (13.3%), school-going children of 6-12 years were more affected and handwashing habit with soap was the key factor to prevent STH infection. The proportion of participants having toilet facility and using footwear regularly had no role in STH prevention.
